Problems solved by technology

Buildings are usually formed by external walls. Although they have a certain sound-proof function, they are far from meeting the noise reduction requirements of urban life, or the sound of elevated traffic, or the noise of shopping malls, and the frequencies and intensities of various sounds are different. , it is more difficult to solve the problem of noise reduction. Therefore, how to set up a structure suitable for noise reduction on the outer walls of buildings outside the city is worth studying.

Abstract

The invention discloses a noise reduction structure for an outer wall of a building, comprising: a first reflective layer laid on the outer surface of the outer wall; a sound-absorbing layer laid on the first reflective layer; a second reflective layer laid laid on the sound-absorbing layer. The invention has the beneficial effect of successively reflecting, absorbing, reflecting, and absorbing the sound wave, and significantly improving the noise reduction function.

Description

technical field [0001] The present invention relates to the field of construction. More specifically, the present invention relates to a noise-reducing structure for an exterior wall of a building. Background technique [0002] An important part of a building is the wall, which is used for bearing, enclosing or separating spaces. Buildings are usually formed by external walls. Although they have a certain sound-proof function, they are far from meeting the noise reduction requirements of urban life, or the sound of elevated traffic, or the noise of shopping malls, and the frequencies and intensities of various sounds are different. , it is more difficult to solve the problem of noise reduction. Therefore, how to set up a structure suitable for noise reduction of outer walls of buildings outside the city is worth studying. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the ...
